SPECIFICATION forming part of Letters Patent No. 759,812, dated May 10, 1904. 7

Application filed February 27, 1904. Serial No- 195,590. (No model.)

To all whom, it may concern.-

Be it known that I, HARRY H. .HAYWARD, a citizen of the United States of America, residing at Monongahela, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Car-W'heels, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to car-wheels, and relates in particular to that class of castmetal wheels used on mine-cars.

The object of my invention is to provide a cast wheel with a removable hub-lining,which receives the end of the axle and which when worn may be quickly replaced, thus rendering the wheel practically as good as new.

In cast wheels of that character to which my improvement relates the hubs are ordinarily formed integral with the rest of the wheel. As the principal wear is on the interior of the hub, the hub-opening soon becomes enlarged to such an extent as to render the wheel no longer [it for use, notwithstanding the fact that the balance of the wheel may be in perfeet condition.

In carrying my invention into effect I provide a wheel having a polygonal opening in its center instead of the usual cylindrical opening for the axle, and in this polygonal opening I fitcorrespondingly-shaped half-sections, which, being formed with circular holes through their centers corresponding in size to the end of the axle, constitute a removable hub-lining, which may be replaced when worn out at comparatively little cost and which will render the wheel to all intents and purposes as good as new.

My invention consists in the novel construction, combination, and arrangement of parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a wheel constructed accord- Fig. 2 is a transverse sectional view of the hub portion of the same, on an enlarged scale. Fig. 3 is a vertical sectional view of the hub portion of my improved wheel, this figure being also on an enlarged scale and the removable hub-lining being omitted. Fig. 4 is a plan view showing a modified form of hub-lining applied to an end of an axle. Fig. 5 is a perspective View, on an enlarged scale, of one of the half-sections of the hublining.

The tread or rim of the wheel 1 is formed with a flange 2 and with radial spokes 3,which connect the rim 1 to the hub portion 1. Six of these spokes are shown in the wheel illustrated in the drawings, and three oil-boxes are disposed around the hub portion 4 at equal distances apart, these oil-boxes being formed integral with the spokes 3 and said hub portion 4:, and the oil-boxes are formed with cavi ties 5, which communicate with a polygonal opening 6 in the center of the hub portion by 5 The hub-lining, which is applied to the hub portion 4, is composed of two similar half-sections, one of which is shown in perspective in Fig. 5. These half-sections consist each of a sleeve 11, shaped to conform with the opening 6 in the center of the hub portion 4, and a flange 12, that is formed with ears 13,arranged at three equidistant points around the edge of the flange and pierced at 14 to receive bolts 15, by means of which the half-sections are maintained in proper position in the hub por- 30 tion. Each of the said half-sections has a circular hole 15 through its center conforming in diameter to that of the axle 16, and the half-section on the inner side of the wheel is formed with an annular flange 17, which has 5 a tapering inner wall and which surrounds a collar 18 on the axle. The inner ends of the sleeve portions 11 of the hub-lining are preferably at right angles to the sleeve portions,

but may in order to effect an even wearing of 9 the axle be cut off diagonally, as shown at 19 in Fig. 5 of the drawings. The inner ends of the sleeves 11 of the half-sections approach close to one another when the half-sections are in position in the wheel withoutmeeting, leaving a space 20, through which the oil from the oil-box, which is provided with port 8, may find its way into the other oil-boxes through the passages 7. The half-sections are applied to the hub portion 4 in such manner that the I00 lugs 13 will face one another, and the bolts 15, which pass through the holes 14: in the ears 13, secure the half-sections against longitudinal movement, rotary movement being of course prevented by the angular shape of the opening 6 and of the sleeves 11. The shaft 16 when in position in the wheel is maintained therein by means of a pin 21.

The half-sections when applied to a wheel constitute a durable hub-lining and they may be made of any suitable material, either the same as that of which the wheel is composed or of a different material. As the wheels are usually made of cast-iron, I propose to form the hub-lining of malleable iron or cast-steel; but bronze, brass, or other metal may be employed, if desired.

From the foregoing description it will be observed that the Wheel proper consists of a single integral casting and that the hub-lining is composed of tWo pieces of comparatively small size, which are easily detached from the Wheel and which may be replaced at a cost very much less than the cost of an entire wheel even where the latter is formed by a single casting.

Having described my invention, I claim 1. In combination with a wheel having a hub, a hub-lining comprising two members, each of which consists of a sleeve carrying a flange on its outer end, the inner ends of the sleeves normally lying adjacent each other, said flanges abutting the outer ends of the hubs, and means secured to each of the flanges for securing the same in normal position.

2. In combination With a Wheel having a hub, a hub-lining comprising two members, each consisting of a sleeve carrying a flange at its outer end, the inner ends of said sleeves being inserted in said hub from the opposite ends thereof.

In testimony whereof I have affixed my signature in the presence of two witnesses.

HARRY H. HAYWVARD.
